I-JCRD2-125 RCD: Ukuvikela Izimpilo Nezakhiwo Ngokuvikeleka Kagesi Okunqamulelayo

Esikhathini lapho ugesi usuyingxenye ebalulekile yokuphila kwethu kwansuku zonke, ukubaluleka kokuphepha kukagesi akunakugcizelelwa. Ngokusetshenziswa okwandayo kwezinto zikagesi nezinhlelo kuzo zombili izindawo zokuhlala nezohwebo, ingozi yezingozi zikagesi nayo iyakhuphuka. Ukuze kuncishiswe lezi zingozi, abakhiqizi basungule imishini yokuphepha kagesi ethuthukisiwe, enye yazo okuyiI-JCRD2-125 RCD(I-Residual Current Circuit Breaker) – idivayisi esindisa impilo eklanyelwe ukuvikela abasebenzisi nezakhiwo ekushayweni kukagesi nemililo engaba khona.

Ukuqonda i-JCRD2-125 RCD

I-JCRD2-125 RCD iyisinqamuli samanje esibucayi esisebenza ngomgomo wokutholwa kwensalela yamanje. Iklanyelwe ngokuqondile ukuqapha isifunda sikagesi nganoma yikuphi ukungalingani noma ukuphazamiseka endleleni yamanje. Uma kwenzeka kuba nokungalingani okutholiwe, njengokuvuza kwamanje phansi, i-RCD iphula ngokushesha umjikelezo ukuze kuvinjelwe ukulimala kubantu ngabanye kanye nokulimala kwempahla.

Le divayisi itholakala ngezinhlobo ezimbili: Uhlobo AC kanye Nohlobo A RCCB (Residual Current Circuit Breaker With Integral Overcurrent Protection). Zombili izinhlobo zenzelwe ukuvikela ukushaqeka kukagesi kanye nezingozi zomlilo kodwa ziyehluka ekuphenduleni kwazo ezinhlotsheni ezithile zamanje.

Thayipha i-AC RCD

Uhlobo lwe-AC RCDs yilona oluvame ukufakwa ezindaweni zokuhlala. Idizayinelwe ukuvikela okokusebenza okuqinile, amandla, noma inductive futhi engenazo izingxenye ze-elekthronikhi. Lawa ma-RCD awanakho ukubambezeleka kwesikhathi futhi asebenza ngaso leso sikhathi lapho ethola ukungalingani kokushintshana kwamandla okusala kwe-sinusoidal.

Thayipha A RCD

Uhlobo A ama-RCD, ngakolunye uhlangothi, ayakwazi ukuthola kokubili ukushintshana kwe-sinusoidal residual current kanye ne-residual pulsating yamanje eqondile efika ku-6 mA. Lokhu kuzenza zifanelekele izinhlelo zokusebenza lapho izingxenye zamanje eziqondile zingaba khona, njengamasistimu wamandla avuselelekayo noma iziteshi zokushaja izimoto zikagesi.

Izici Eziyinhloko Nezinzuzo

I-JCRD2-125 RCD inezinhlobonhlobo zezici ezihlaba umxhwele ezithuthukisa ukusebenza kwayo nokuthembeka. Nazi ezinye zezinto zayo ezivelele:

Uhlobo lwe-Electromagnetic: I-RCD isebenzisa isimiso sikazibuthe kagesi ukuze ibone futhi iphendule kumaza asalayo, iqinisekisa ukuvikeleka okusheshayo nokunembile.

Ukuvikelwa Kokuvuza Komhlaba:Ngokuqapha ukugeleza kwamanje, i-RCD ingathola futhi inqamule isifunda uma kwenzeka ukuvuza komhlaba, ukuvimbela ukushaqeka kukagesi kanye nezingozi zomlilo.

Ukuphula Amandla: Ngomthamo wokuphuka ofika ku-6kA, i-JCRD2-125 ingakwazi ukusingatha imisinga yamaphutha aphezulu, inikeze ukuvikeleka okuqinile kumasekhethi amafushane nokulayishwa ngokweqile.

Ilinganiselwe Izinketho Zamanje: Itholakala kuma-currents ahlukahlukene alinganisiwe kusukela ku-25A kuya ku-100A (25A, 32A, 40A, 63A, 80A, 100A), iI-RCDingalungiswa ukuze ivumelane nezinhlelo nemithwalo kagesi ehlukene.

Ukuzwela Kokuhamba: Idivayisi inikezela ngemizwa yokukhubeka engu-30mA, 100mA, kanye ne-300mA, ihlinzeka ngokuvikeleka okwengeziwe ekuthinteni okuqondile, ukuthintana okungaqondile, nobungozi bomlilo, ngokulandelana.

Oxhumana naye Wenkomba Yesimo Esihle: Othintwayo obonisa isimo esihle uvumela ukuqinisekiswa kalula kwesimo sokusebenza se-RCD.

35mm DIN Rail Mounting: I-RCD ingafakwa kumzila wesitimela we-DIN ongu-35mm ojwayelekile, ohlinzeka ngokuguquguquka kokufakwa kanye nokusebenziseka kalula.

Ukufaka Ukuvumelana nezimo: Idivayisi inikeza ukukhetha kokuxhumeka kolayini kusukela phezulu noma phansi, okuhlanganisa izintandokazi zokufaka ezihlukene kanye nezidingo.

Ukuhambisana Namazinga: I-JCRD2-125 ithobelana namazinga e-IEC 61008-1 kanye ne-EN61008-1, iqinisekisa ukuthi ihlangabezana nezidingo zomhlaba jikelele zokuphepha nokusebenza.

Ukucaciswa Kwezobuchwepheshe kanye Nokusebenza

Ngokungeziwe ezicini zayo ezibalulekile, i-JCRD2-125 RCD inezicaciso zobuchwepheshe ezihlaba umxhwele ezithuthukisa ukuthembeka nokusebenza kwayo. Lokhu kubandakanya:

• Ikalwe I-Voltage Yokusebenza: 110V, 230V, 240V ~ (1P + N), okwenza ifanelekele ukusetshenziswa ezinhlelweni ezahlukene zikagesi.
• I-Insulation Voltage: 500V, iqinisekisa ukusebenza okuphephile ngisho nangaphansi kwezimo zamandla kagesi aphezulu.
• Imvamisa elinganiselwe: 50/60Hz, iyahambisana namaza kagesi ajwayelekile.
• I-Impulse Elinganiselwe Imelana ne-Voltage (1.2/50): 6kV, ihlinzeka ngokuvikeleka okuqinile kuma-voltage adlulayo.
• Iziqu Zokungcolisa:2, ilungele ukusetshenziswa ezindaweni ezinokungcola okusesilinganisweni.
• Impilo Yemishini Nekagesi:Izikhathi ze-2,000 nezikhathi ze-2000, ngokulandelana, ukuqinisekisa ukuqina nokuthembeka kwesikhathi eside.
• Idigri Yokuvikela: IP20, ehlinzeka ngokuvikelwa okuyisisekelo ekuthinteni nezingxenye eziyingozi.
• I-Ambient Temperature: -5℃~+40℃ (ngesilinganiso sansuku zonke ≤35℃), okuvumela ukusetshenziswa ebangeni elibanzi lezimo zemvelo.
• Inkomba Yendawo Yokuxhumana: Okuluhlaza=KUVALIWE, Okubomvu=KUVULIWE, okunikeza inkomba ecacile yokubuka isimo se-RCD.
• Uhlobo Lokuxhuma Kwetheminali: Ibha yebhasi yohlobo lwekhebula/yephini, ehlalisa izinhlobo ezahlukene zokuxhunywa kukagesi.

Ukuhlola Nokwethenjwa Kwangaphakathi Kwesevisi

Ukuqinisekisa ukwethembeka kwama-RCD kubalulekile ekusebenzeni kwawo ngempumelelo ekuvikeleni izingozi zikagesi. Abakhiqizi benza ukuhlola okuqinile phakathi nenqubo yokukhiqiza, eyaziwa ngokuthi ukuhlola uhlobo, ukuze kuqinisekiswe ukusebenza kwedivayisi ngaphansi kwezimo ezihlukahlukene. Ama-RCD ohlobo A, B, kanye no-F ahlolwa ngendlela efanayo ne-AC RCD, enemininingwane yenqubo yokuhlola kanye nezikhathi eziphezulu zokunqanyulwa ezichazwe kumazinga omkhakha afana ne-IET Guidance Note 3.

Ngesikhathi sokuhlolwa kukagesi, uma umhloli ethola Uhlobo lwe-AC RCD futhi ekhathazekile ngomthelela ongase ube khona wensalela yamanje ye-DC ekusebenzeni kwayo, kufanele azise iklayenti ngezingozi ezingaba khona futhi atuse ukuhlolwa kwenani lensalela yephutha le-DC. Kuye ngezinga lensalela yephutha le-DC, i-RCD ephuphuthekiswe yiyo ingase yehluleke ukusebenza, ibeke ingozi enkulu yokuphepha.

Isiphetho

Kafushane, iI-JCRD2-125 RCDiyithuluzi elibalulekile lokuphepha likagesi elinikeza ukuvikeleka okuphelele ekushayweni kukagesi nasezingozini zomlilo. Izici zayo ezithuthukisiwe, ezihlanganisa ukutholwa kozibuthe kagesi, ukuvikelwa kokuvuza komhlaba, namandla okuphuka okuphezulu, kuyenza ibe inketho efanelekile ukuthi isetshenziswe ezindaweni zokuhlala nezohwebo. Ngokuhambisana nezindinganiso zamazwe ngamazwe kanye nezinqubo zokuhlola eziqinile, i-JCRD2-125 RCD inikeza abasebenzisi ukuthula kwengqondo kanye nezinga eliphezulu lokuqinisekisa ukuphepha. Njengoba ugesi uqhubeka udlala indima ebalulekile ekuphileni kwethu kwansuku zonke, ukutshala imali emishinini yokuphepha kagesi ethuthukisiwe njenge-JCRD2-125 RCD kuyisinqumo esihlakaniphile esingasindisa izimpilo futhi sivikele izakhiwo ezingozini zikagesi ezibhubhisayo.
